(516) Area Code Business Phone Numbers
A 516 number tells customers you're rooted in Nassau County and Long Island's South Shore, from Freeport's waterfront to Garden City's business corridor. Established in 1951, it's one of the original Long Island area codes and still carries real weight with locals.

The 516 originally blanketed all of Long Island when it debuted in 1951. That changed in 1999 when Suffolk County split off into its own 631 code, leaving 516 to cover Nassau County exclusively [1]. If someone sees a 516 on caller ID, they're picturing towns like Freeport, Hempstead, and Hicksville, not the rest of the island.
Freeport itself is home to roughly 44,148 people [2], and its economy leans on healthcare, retail, and a busy waterfront trade tied to the Nautical Mile. Zoom out and Long Island produced about $558 billion in GDP in 2024, roughly 20% of the entire New York metro area's economic output [3]. That's a lot of buying power packed into two counties.
For a small business here, a 516 number is basically table stakes. Nassau residents tend to trust local, and a 917 or 800 number can quietly cost you the callback. A Tonet 516 line puts you on the same footing as the plumber, the pediatric dentist, and the pizza spot down the block.
Cities Served by the 516 Area Code
The 516 covers all of Nassau County, from Elmont and Valley Stream near the Queens border out to Massapequa and Plainview. Here are some of the largest cities and villages inside its footprint.

Frequently Asked Questions
Can I get a 516 number if my business isn't physically in Nassau County?
Yes. Tonet numbers are cloud-based, so you can pick a 516 number no matter where your office is. Plenty of Queens and Brooklyn businesses grab a 516 to look local to their Nassau customer base.
Is 516 the only area code for Nassau County?
Nassau County was 516-only for decades. A 363 overlay was later added for new numbers, but 516 is still the recognizable, in-demand code for the area and what most established local businesses use.
Can I port my existing 516 number to Tonet?
Yes, porting is free and usually takes 5 to 10 business days. Your current number keeps working the whole time, so you don't miss a call from a regular in Oceanside or Baldwin.
How much does a 516 business line cost?
Plans start at $10 per user per month, billed daily. Extra local numbers are $2.50 per month each, and there are no contracts or annual commitments.
Do I need special hardware to use a 516 VoIP number?
No. It runs on any laptop, desk phone, or smartphone with the Tonet app. All you need is a decent internet connection, which is easy to come by anywhere in Nassau.
